Useless Crazy Concubine: the Evil King Pampers His Secret Service Concubine

What's not good is that both the male and female protagonists are holy mothers. Those who have harmed them are spared every time, and then let them continue to be evil. The female protagonist is even more clear about which people have problems. It's just their meaningful eyes that make them think they are powerful. In fact, they don't take any precautions and wait for others to harm them, many times. Just read it when you are bored. It will easily make people angry. It is not recommended.

It's beautiful and well written. Now I'm reading it for the second time.
